Banknote handling apparatus

1. A banknote handling apparatus for recognizing and handling banknotes, the apparatus comprising: a depositing unit configured to deposit the banknotes; a dispensing unit configured to dispense the banknotes; a plurality of banknote storing units configured to store the banknotes; a transport unit configured to transport the banknotes; a recognition unit provided at the transport unit, and configured to recognize the banknotes; a control unit configured to control the handling of the banknotes; and a portion for an optional attachment to which an escrow unit temporarily storing the banknotes in a process of the handling is selectively attachable, wherein the control unit includes an option control unit performing control corresponding to an attached state of the escrow unit, and control corresponding to an unattached state.

2. The banknote handling apparatus of claim 1 , wherein the option control unit has common firmware corresponding to both of the attached and unattached states of the escrow unit, and the firmware is switchable between a first mode of performing the control corresponding to the attached state of the escrow unit, and a second mode of performing the control corresponding to the unattached state of the escrow unit.

3. The banknote handling apparatus of claim 2 , wherein when the escrow unit is attached, the control corresponding to the unattached state is performed by switching the firmware from the first mode to the second mode.

4. The banknote handling apparatus of claim 2 , further comprising: an option detection unit configured to detect attachment of the escrow unit based on presence or absence of electrical connection or communications of the escrow unit.

5. The banknote handling apparatus of claim 4 , further comprising: an error alarm unit configured to notify an error when the firmware is switched to the first mode although the attachment of the escrow unit is not detected by the option detection unit.

6. A banknote handling apparatus for recognizing and handling banknotes, the apparatus comprising: a depositing unit configured to deposit the banknotes; a dispensing unit configured to dispense the banknotes; a plurality of banknote storing units configured to store the banknotes; a transport unit configured to transport the banknotes; a recognition unit provided at the transport unit, and configured to recognize the banknotes; a control unit configured to control the handling of the banknotes; and a chamber for an optional attachment, wherein none of the plurality of banknote storing units are located in the chamber for the optional attachment, a cassette attachable to and detachable from the banknote handling apparatus with the banknotes stored, or an additional storing unit provided in addition to the banknote storing units, is selectively attachable to the chamber for the optional attachment, the chamber for the optional attachment is switchable among an attached state of the cassette, an attached state of the additional storing unit, and an unattached state of the cassette and the additional storing unit, and the control unit includes an option control unit performing control corresponding to the attached state of the cassette, the attached state of the additional storing unit, or the unattached state of the cassette and the additional storing unit.

7. The banknote handling apparatus of claim 6 , wherein the option control unit has common firmware corresponding to the attached state of the cassette, the attached state of the additional storing unit, and the unattached state, and the firmware is switchable among a first mode of performing the control corresponding to the attached state of the cassette, a second mode of performing the control corresponding to the attached state of the additional storing unit, and a third mode of performing the control corresponding to the unattached state of the cassette and the additional storing unit.

8. The banknote handling apparatus of claim 7 , wherein when the cassette or the additional storing unit is attached, the control corresponding to the unattached state is performed by switching the firmware to the third mode.

9. The banknote handling apparatus of claim 7 , further comprising: an option detection unit configured to detect attachment of the cassette or the additional storing unit based on presence or absence of electrical connection or communications of the cassette or the additional storing unit.

10. The banknote handling apparatus of claim 9 , further comprising: an error alarm unit configured to notify an error when the firmware is switched to the first mode or the second mode although the attachment of the cassette or the additional storing unit is not detected by the option detection unit.

11. The banknote handling apparatus of claim 6 , wherein the cassette includes a first frame supporting the cassette, the additional storing unit includes a second frame supporting the additional storing unit, and the chamber for an optional attachment includes a frame fixing unit for attachment of the first frame and the second frame.

12. A banknote handling apparatus recognizing and handling banknotes, the apparatus comprising: a depositing unit configured to deposit the banknotes; a dispensing unit configured to dispense the banknotes; a plurality of banknote storing units configured to store the banknotes; a transport unit configured to transport the banknotes; a recognition unit provided at the transport unit, and configured to recognize the banknotes; a control unit configured to control the handling of the banknotes; a portion for an optional attachment to which an escrow unit temporarily storing the banknotes in a process of the handling is selectively attachable; and a chamber for an optional attachment to which a cassette attachable to and detachable from the banknote handling apparatus with the banknotes stored, or an additional storing unit provided in addition to the banknote storing units is selectively attachable, wherein the control unit includes an option control unit performing control corresponding to an attached state of the escrow unit, control corresponding to an unattached state of the escrow unit, control corresponding to an attached state of the cassette or the additional storing unit, and control corresponding to an unattached state of the cassette or the additional storing unit.

13. The banknote handling apparatus of claim 12 , wherein the option control unit has common firmware corresponding to both of the attached and unattached states of the escrow unit, and the attached state of the cassette, the attached state of the additional storing unit, and the unattached state, the firmware is switchable between a first mode of performing the control corresponding to the attached state of the escrow unit, and a second mode of performing the control corresponding to the unattached state of the escrow unit, and the firmware is switchable among a third mode of performing the control corresponding to the attached state of the cassette, a fourth mode of performing the control corresponding to the attached state of the additional storing unit, and a fifth mode of performing the control corresponding to the unattached state of the cassette and the additional storing unit.
